Abstract The carrier and BST solid superacid catalyst of the high specific surface area are obtained by the method of shaped nanocells,which are shaped after the alkali-earth metal's carbonate in the pottery-balls has been solved by thin hydrochloric acid.BST-catalyst is used in the synthesis of glyceryl triacetate.The experiment results show:the catalyst activity increases with specific surface area of BST-catalyst shaped by the same alkali-earth metal's carbonate,while it doesn't increase when the cell is shaped by the no same carbonate.The highest activity is got when the cell is shaped by SrCO_3.
